Adding tags to an article, product, property or any other items, helps organize these items that have some similarities or are related in some way or another. On your website, when you click on a tag, it will take you to a "search page" with a list of all items matching this tag. Tags are separated by use of comma. In other words, you can write a single word, or a short phrase. While you are typing in a new tag, suggestions of existing tags will show up in the list.
Examples of use:Articles: us politics, climate change, usa
